Objective: This study was designed to analyze the clinical features of idiopathic pulmonary fibrosis patients who attended a Korean medicine hospital and the treatment effects through retrospective chart reviews. Methods: The medical records of 82 outpatients who had been diagnosed with idiopathic pulmonary fibrosis and visited the Allergy, Immune, and Respiratory System Department of Kyung Hee Korean Medicine Hospital from 8 January 2015 to 8 January 2021 were retrospectively reviewed. To assess the treatment outcomes, we used the FVC (Forced Vital Capacity), DLCO (Diffusing capacity of the Lung for CO), 6-minute walk test, and HRCT (High Resolution Computed Tomography). Results: The study group consisted of 28 females and 54 males. The median age of the patients was 67.98±11.44 years. The chief complaints were cough (n=51) and dyspnea (n=49). Other frequent symptoms were general weakness (n=8), weight loss (n=4), and a fever (n=2). A total of 77 (93.90%) patients were prescribed Korean herbal medicine, and 52 (63.41%) patients were treated with acupuncture, moxibustion, cupping therapy, ICT, or pharmacopuncture. After treatments, FVC, DLCO, the 6-minute walk test, and HRCT were maintained or worsened slightly. Conclusions: This study presented the characteristics of idiopathic pulmonary fibrosis patients treated by Korean medical therapies, and further studies of Korean medical treatments for idiopathic pulmonary fibrosis patients would be valuable.

Background : The Antimicrobial Stewardship Program promotes interdisciplinary interventions and targeted recommendations for the proper utilization of antibiotics. In particular, the aim of the program is to avoid indiscriminate use of broad-spectrum antibiotics based on the documented literature on the significant impact of unsystematic usage of antibiotics on the distribution of antibiotic-resistant microorganisms. To improve the care process for pneumonia treatment using antimicrobial agents, institution-level guidelines were established and disseminated at the Seoul National University Bundang Hospital in April 2016. In this study, we evaluated changes in the physicians'antibiotic prescribing patterns both before-and after-the implementation of the guidelines. Methods : The electronic medical records of inpatients who were prescribed with one or more antibiotics in May 2014 (Group A) and May 2016 (Group B) were reviewed. Data on demographic characteristics, clinical outcomes, and antibiotic prescriptions were collected and the prescription records were compared both before- and after- the implementation of the guidelines. Results : A total of 180 patients were included in the study: 77 patients in group A and 103 patients in group B. The baseline characteristics of the patients were not significantly different between the two groups. Community-acquired pneumonia was the most common diagnosis in both the groups and the difference was not significant (68.8% vs. 67.9%; p=0.67). The type of antibiotic prescriptions used for empirical treatment was not different between the two groups. The most commonly prescribed empirical antibiotics were cephalosporins, with no significant difference (p=0.31). One of the most inappropriately used antibiotics was piperacillin/tazobactam and the rate of prescription was similar in both the groups (p=0.68). The rates of appropriate empirical selection of antibiotics remained unaltered between the two groups (67.5% vs. 71.8%; p=0.53). Conclusions : Implementation of the guidelines only exhibited no significant effect on the antibiotic prescribing patterns of physicians for the treatment of pneumonia. To improve the adequate use of empiric antibiotics, more active interventions and closer monitoring of the feedbacks should be additionally considered and evaluated in future studies.

This study aimed to define the diagnostic criteria for cervicogenic headache and propose an efficient method of clinical evaluation and physical therapy. Fifteen patients with cervicogenic headache and 15 healthy individuals were recruited and categorized into the test group and the control group, respectively. The groups were compared in terms of muscle characteristics, muscle activity and posture, and the intervariable correlations were analyzed for the test group. A significant between-group difference was found in the stiffness of the suboccipital muscle and the tone and stiffness of the upper trapezius muscle (p<.001). In posture comparison, a significant difference was noted in neck tilt angle and the T1 slope angle (p<.05). The activity of the sternocleidomastoid muscle was also significantly different between the groups (p<.001). When the correlations among the muscle characteristics, the posture, and the activity of the sternocleidomastoid muscle were analyzed for the test group, a positive correlation was found between the tone and the stiffness of the suboccipital muscle (p<.001) and between the tone and the stiffness of the upper trapezius muscle (p<.001). The findings of this study suggest a more efficient approach for the assessment and treatment of cervicogenic headache patients. It is considered that, further studies including more subjects of various job categories and comparing the outcomes.

Objective: Using domestic cats as a biomedical research model for fertility preservation, the present study aimed to characterize the influences of ovarian tissue encapsulation in biodegradable hydrogel matrix (fibrinogen/thrombin) on resilience to cryopreservation, and static versus non-static culture systems following ovarian tissue encapsulation and cryopreservation on follicle quality. Methods: In experiment I, ovarian tissues (n=21 animals; 567 ovarian fragments) were assigned to controls or hydrogel encapsulation with 5 or 10 mg/mL fibrinogen (5 or 10 FG). Following cryopreservation (slow freezing or vitrification), follicle viability, morphology, density, and key protein phosphorylation were assessed. In experiment II (based on the findings from experiment I), ovarian tissues (n=10 animals; 270 ovarian fragments) were encapsulated with 10 FG, cryopreserved, and in vitro cultured under static or non-static systems for 7 days followed by similar follicle quality assessments. Results: In experiment I, the combination of 10 FG encapsulation/slow freezing led to greater post-thawed follicle quality than in the control group, as shown by follicle viability (66.9%±2.2% vs. 61.5%±3.1%), normal follicle morphology (62.2% ±2.1% vs. 55.2%±3.5%), and the relative band intensity of vascular endothelial growth factor protein phosphorylation (0.58±0.06 vs. 0.42±0.09). Experiment II demonstrated that hydrogel encapsulation promoted follicle survival and maintenance of follicle development regardless of the culture system when compared to fresh controls. Conclusion: These results provide a better understanding of the role of hydrogel encapsulation and culture systems in ovarian tissue cryopreservation and follicle quality outcomes using an animal model, paving the way for optimized approaches to human fertility preservation.

Background: We aimed to investigate the analgesic efficacy of an erector spinae plane block (ESPB) in immediate breast reconstruction (IBR) with a tissue expander. Methods: Adult women undergoing IBR with a tissue expander after mastectomy were randomly assigned to either intravenous patient-controlled analgesia (IV-PCA) alone (group P) or IV-PCA plus ESPB (group E). The primary outcome was the total amount of opioid consumption during 24 hours postoperatively between the two groups. Secondary outcomes were patient satisfaction, pain score at rest and on shoulder movement using numerical rating scale, incidences of postoperative nausea and vomiting (PONV), and a short form of the brief pain inventory (BPI-SF) at 3 and 6 months after surgery between the groups. Results: Fifty eight patients completed the study. At 24 hours postoperatively, total opioid consumption was significantly less in group E than in group P (285.0 ± 92.0, 95% confidence interval [CI]: 250.1 to 320.0 vs. 223.2 ± 83.4, 95% CI: 191.5 to 254.9, P = 0.005). Intraoperative and cumulative PCA fentanyl consumption at 3, 6, 9, and 24 hours were also less in group E than in group P (P = 0.004, P = 0.048, P = 0.020, P = 0.036, and P < 0.001, respectively). Patient satisfaction was higher in group E (6.9 ± 1.8 vs. 7.8 ± 1.4, P = 0.042). The incidences of PONV was similar. Conclusions: The ESPB decreased postoperative opioid consumption and increased patient satisfaction without significant complications after IBR with a tissue expander after mastectomy.

Purpose: The purpose of this meta-analysis was to examine the high-level evidence of the effects of manual therapy on musculoskeletal diseases. Methods: Domestic databases were searched for studies that conducted clinical trials associated with manual therapy on chronic musculoskeletal diseases. A total of 591 studies published between 2005 and 2018 were identified, with 18 studies satisfying the inclusion data. The studies were classified according to patient, intervention, comparison, and outcome (PICO). The search outcomes were items associated with pain and physical function. The 18 studies included in the study were evaluated by using the R meta-analysis (version 4.0). The quality of 18 randomized control trials was evaluated by using the Cochrane risk of bias (ROB). The effect sizes were computed as the corrected standardized mean difference (SMD). Subgroup and meta-regression analyses were also used. Egger's regression test was carried out in order to analyze the publication bias. Cumulative meta-analysis and sensitivity analysis were also conducted in order to analyze the data error. Results: The following factors showed the large effect size of manual therapy on chronic musculoskeletal diseases: pain (Hedges's g = 2.66; 95% CI = 1.47 ~ 3.85), and physical function (Hedges's g = 2.15; 95% CI: 1.22 ~ 3.08). The subgroup analysis only showed a statistical difference in the type of manual therapy (pain) and outcome (physical function). No statistically significant difference was found in the meta-regression analysis. Publication bias was found in the data, but the results of the trim-and-fill method showed that such bias did not largely affect the obtained data. Furthermore, there were no data errors in the cumulative meta-analysis and sensitivity analysis. Conclusion: This study provides evidence for the effectiveness of manual therapy on chronic musculoskeletal diseases in pain and physical function. Subgroup analysis suggests that only the type of manual therapy for pain and the type of outcome for physical function differed in effect size.

Purpose : The purpose of this meta-analysis was to evaluate the effects of transcranial direct current stimulation on the lower extremity function of stroke patients. Methods : Domestic data were gathered from studies that conducted clinical trials associated with transcranial direct current stimulation and its impact on lower extremity function of stroke patients. A total of 592 studies published between 2012 and 2020 were identified, with 7 studies satisfying the inclusion data. The studies consisted of patient, intervention, comparison, and outcome (PICO) data. The search outcomes were items associated with muscle activity, balance, muscle strength and walking ability. Cochrane risk of bias (ROB) was used to evaluate the quality of 3 randomized control trials. The quality of 4 non-randomized control trials was evaluated using risk of bias assessment tool for non-randomized studies (RoBANS). Effect sizes in this study were computed as the corrected standard mean difference (SMD). A random-effect model was used to analyze the effect size because of the high heterogeneity among the studies. Egger's regression and 'trim-and-fill' tests were carried out to analyze the publishing bias. Results : The following factors had a large total effect size (Hedges's g=2.10, 95 %CI=1.54~2.66) involving transcranial direct current stimulation on stroke patients: muscle activity (Hedges's g=2.38, 95 %CI=1.08~3.68), balance (Hedges's g4=2.41, 95 %CI=1.33~3.60), walking ability (Hedges's g=1.54, 95 %CI=0.49~2.59), and muscle strength (Hedges's g=2.45, 95 % CI: 0.85~4.05). Egger's regression test showed that the publishing bias had statistically significant differences but 'trim-and-fill' test showed that there was still statistical difference. Conclusion : This study provides evidence for the effectiveness of transcranial direct current stimulation on the lower extremity in terms of muscle activity, balance, walking ability, and muscle strength in stroke patients. However, due to the low quality of studies and high heterogeneity factors, the results of our study should be interpreted cautiously.

Toxic megacolon is a fatal complication of inflammatory or infectious bowel disease. Prognosis depends on the severity of the disease. In cases of poor prognosis, clinical outcomes range from intestinal resection to death, so early diagnosis and appropriate treatment are very important. However, the prevalence of toxic megacolon in children is very low, and in those without underlying diseases such as inflammatory bowel disease, early diagnosis may be delayed. A previously healthy 12-year-old boy presented to our hospital with lower abdomen pain, fever, and hematochezia. Despite antibiotic therapy, the symptoms worsened. On the third day, abdominal computed tomography revealed severe dilatation of the transverse colon, which indicated toxic megacolon. Stool culture was positive for Salmonella enteritidis group D, and rectal endoscopy showed no signs of inflammatory bowel disease. Ceftriaxone and intravenous methylprednisolone were administered, and the patient's condition improved without any complications. We report a case of toxic megacolon as a complication of infectious colitis caused by S. enteritidis group D, which was diagnosed using early imaging and successfully treated without surgical intervention.

Purpose: Patients with hematologic malignancy (HM) typically have a high mortality rate when their condition deteriorates. The chronic progressive course of the disease makes it difficult to assess the effect of intervention on acute events. We investigated the effectiveness of a rapid response team (RRT) on in-hospital mortality in patients with HM. Methods: We retrospectively analyzed the data of patients with HM who admitted to the medical intensive care unit between 2006 and 2015. Clinical outcomes before and after RRT implementation were evaluated. Results: A total of 228 patients in the pre-RRT period and 781 patients in the post-RRT period were included. The overall in-hospital mortality was 55.4%. Patients in the post-RRT period had improved survival; however, they required more vasopressor therapy, continuous renal replacement therapy, and extracorporeal membrane oxygenation. Multivariate analysis revealed that in-hospital mortality was associated with RRT activation (hazard ratio [HR], 0.634; 95% confidence interval [CI], 0.498-0.807; p < .001), neurological disease (HR, 2.007; 95% CI, 1.439-2.800; p < .001), sequential organ failure assessment score (HR, 1.085; 95% CI, 1.057-1.112; p < .001), need for continuous renal replacement therapy (HR, 1.608; 95% CI, 1.206-1.895; p< .001), mechanical ventilation (HR, 1.512; 95% CI, 1.206-1.895; p< .001), vasopressor (HR, 1.598; 95% CI, 1.105-2.311; p = .013), and extracorporeal membrane oxygenation (HR, 1.728; 95% CI, 1.105-2.311; p = .030). Conclusion: RRT activation may be associated with improved survival in patients with HM.

Digital technology is gradually expanding its field and has a great influence on various fields of dentistry. Recently in digital dentistry, the importance of superimposing various 3-dimensional (3D) image data is emerging, in order to utilize gathered data effectively for diagnosis and prosthesis fabrication. Integrating data from facial scans, intraoral scans, and mandibular movement recordings can create a virtual patient. A virtual patient is formed by integrating digital 3D diagnostic data such as intraoral and extraoral soft tissues, residual dentition, and dynamic occlusion, and the results of prosthetic treatment can be evaluated virtually. The patients in this case report were a 37-year-old female whose chief complaint is that the appearance of the existing prosthesis was distorted and a 55-year-old female patient whose anterior prosthesis needed to be refabricated after the endodontic treatment. 3D facial scans were obtained from each patient, and the patient's mandibular movements were recorded using ARCUS Digma 2 (KaVo Dental GmbH, Biberach an der Riss, Germany). The collected data were integrated on computer-aided design (CAD) software (Exocad dental CAD; exocad GmbH, Darmstadt, Germany) and transferred to a virtual articulator to create a digital virtual patient. The temporary fixed prostheses were designed, restored, and evaluated, and it was reflected into the final restorations. With the aid of the virtual dental patient, accuracy and predictability could be increased throughout treatment, simplifying the occlusal adjustment and clinical evaluation with improved esthetic outcomes.
